Figs. 14 and 15 are, respectively, full and sectional which it can beeasily removed by the fingers and another type elernent snapped intoplace. Change of ele-v ments does not require the removal of the clipfrom the type bar and one of the functions of the tongue 24 is toprevent the clip from slipping out of the slot 18 of the type bar duringthe replacing operations.

In Figs. '7, 8, and 9 the type bar 50 is adapted to hold two typeelements 51 and-52, and is provided with a cylindrical or full guide orhinge stud 53 and a semicylindrical or half guide stud 54. The latterprovides the clearance necessary to allow the type 51 to be swung aboutits stud 53 when it is being removed and also makes it possible to spacethe type elements the proper distance vertically of the charactersthereof. The type bar 50 is shaped to provide an enlarged striking head56 which is slotted inwardly as at 57 from its outer end and parallel toa flat face 58 which has spaced notches 59 therein for the reception ofsuitable keys 61 projecting from the bottom of the slot 62 formed ineach type element. The sides 63 of each type element are provided withpockets 64 or depressions into which seat the nubs 66 of the clips 67.The latter may or may not be provided with tongues as is the clip 26,but are substantially U-shaped and are tempered so that the sidesthereof converge to provide gripping jaws for holding the type elementsin place. The sides of each type element are tapered and the edgesbevelled as described in connection withtthe element so that the typecan be snapped into place with a minimum of effort.

Suitable clearances are provided between the top of the slots in thetype elements and the finished face of the type bar, so that when theform of clip 26 is used the tongue 24 provides a cushioning effect whenthe type strikes the platen, and the combined action of said tongue andthe trunnion effect of the nubs makes the type selfseating at platenimpact so that a clear type impression is produced. The type elements ofeach form have recesses for the studs in each side and the studs have adrive fit with a hole in the type bar so that the stud can be used atone side of the type bar or the other to engage the type elements asused on the right or left hand type bars. The clips may be secured inplace by the swaged spots 65 which crowd the metal of the slot and blockexit of the clips.

-In the form of the invention shown in Figs. 12 and 13, the clip 70 ismade the same as the clip 26 except for the tongue 24. It is fixed inplace in the slot 71 of the type bar 72 by swaging the metal of the typebar as at 73 to crowd the metal of the type bar and jam the clip inplace. A shoulder or flange 74 formed at the ends and sides of the typeelement 76 permits the use of a simplified pick-off tool 77 whose legs78 can be spread so that the turned lower ends 79 thereof, notched as at80, can snap beneath the flange 74 of the type element. When the tool isrocked in counterclockwise direction the type is lifted out ofengagement with the clip and can be readily removed from the type bar.

In Fig. 14 the clip 81 is held in place by a spot of solder 82, and inFig. 15 the method of fixing the clip 83 in the slot 84 is by swagingthe outer edges of the material at the end of the slot as at 85. Thisfigure also illustrates the clearance between the sides and bottom ofthe key 86 of the type 87 and the notch 88 so that the floating effectof the type is obtained, particularly when a clip, having a tongue, isemployed.

It is to be noted that the clip 26 with its tongue 24, can be used inthe slot 84 which does not need to be recessed as at 22, with the end ofthe slot being restricted as by swaging 85 so that the cushioning effectof the tongue gives further floating and self-seating advantages to thetype mounting.

While I have described whatI consider to be highly desirable embodimentsof my invention, it is obvious that many changes in form could be madewithout departing from the spirit of the invention, and I therefore, donot limit myself to the exact forms herein shown and described nor toanything less than the whole of my invention as hereinbefore set forth,and as hereinafter claimed.
